A conventional lender asks what you earn. A DSCR lender asks what the property earns. For an investor holding several properties, that difference is the whole reason the product exists.

Conventional underwriting applies personal-income, debt-to-income, and financed-property rules. Those rules can constrain a growing portfolio even when the rentals perform. DSCR lending instead leads with each property's income, while still applying the lender's other borrower and property requirements.

Use this checklist with the DSCR loan program and the DSCR calculator. If you are deciding between property-income underwriting and personal-income underwriting, start with the DSCR versus conventional comparison.

The ratio

Debt service coverage ratio is net operating income divided by debt service.

In day to day use: monthly rent divided by the total monthly payment, where the payment includes principal, interest, taxes, insurance, and any HOA dues.

A property renting for $2,400 with an all in payment of $2,000 has a DSCR of 1.20. It produces 20% more income than it needs to service the debt.

  • Below 1.0. The property does not cover the modeled payment from rent alone.
  • At 1.0. Rent and the modeled payment are equal.
  • Above 1.0. The property has a coverage cushion, and that cushion grows as the ratio rises.

The minimum ratio, leverage, and pricing treatment are program-specific. Do not treat an example band as an approval. Use the threshold in the written terms.

What underwriting actually reads

Rent. The lower of the executed lease or the appraiser's market rent opinion. An above market lease to a friend does not raise the number. On a vacant property, market rent from the appraisal carries the file.

Taxes and insurance. Actual figures, not estimates. Watch for reassessment after a sale, which is a common way a projected 1.25 arrives as a 1.08. If the jurisdiction reassesses on transfer, underwrite the post sale bill.

HOA. Included in full.

Vacancy and management. Some lenders apply a haircut, others use gross rent. It is worth asking, because it moves the answer.

Your credit and reserves. Credit still prices the loan. Reserves are usually six months of payments, more on a vacant property.

Property condition. DSCR is a stabilised product. A property mid renovation does not qualify; it needs a bridge loan first, then a DSCR refinance once it is rented, which is exactly the shape of a BRRRR.

Fixing a file that misses

If the ratio comes in short, there are only four levers, and they are not equally useful.

Reduce the loan amount. Lower leverage lowers the payment and lifts the ratio directly. This is the most reliable fix and the most expensive in cash.

Extend amortisation. A 30 year schedule pays less monthly than a 20. Some lenders offer interest only, which raises DSCR meaningfully because there is no principal in the payment. Understand that you are improving a ratio without improving the property.

Raise the rent, legitimately. If the unit is genuinely under market and the lease is expiring, a renewal at market changes the file. This takes months, and it has to be real, because the appraiser's market rent will contradict a paper increase.

Appeal the assessment. Slow, but on an over assessed property it permanently improves the ratio and the returns underneath it.

What does not work is arguing the ratio. It is arithmetic on figures the lender verifies independently.

Terms that still matter

Qualifying on the property's income does not make the rest of the term sheet secondary. Read the leverage, amortisation, reserve requirement and exit terms together. The dedicated DSCR versus conventional comparison explains when personal-income underwriting is still the better fit.

Check the written prepayment terms. Whether a DSCR loan has a prepayment provision, and whether it uses a step-down schedule, depends on the lender, program, note, state, and loan purpose. If you expect to sell or refinance early, price the exit from the actual term sheet before signing.

For a refinance, review BRRRR refinance seasoning before choosing the closing date. Ohio properties also have a market-specific DSCR guide.

Before you apply

Run the property through the DSCR calculator. It computes the ratio from rent, the loan, the rate, amortisation, taxes, insurance, and HOA, which is the same arithmetic underwriting performs, and it will tell you immediately where the property stands. Compare that result with the lender's written threshold and the rest of its credit, reserve, property, and documentation rules.

If the full file fits the program, send it over. Written terms inside 24 to 48 hours.
